ADE 1.7 only supports one activation on the computer or the device.
You can deactivate a computer by hitting Ctrl (Cmd on Mac) Shift D. You can deactivate a connected device by hitting Ctrl (Cmd on Mac) Shift E.
Please Note: Deactivating a computer/device does not get you an activation back (once you use it, it is gone).
Unless you truly want to manage the content seperately, I would suggest that consolidate to a single AdobeID (and just give up on the content on the other ID).
Thank you for your reply.
I have two more questions:
1) how can I join my 2 ID counts without loosing my ebook?
2) Now my reader is activated with my ID count. On my windows comuter, I can see it on Adobe Digital edition and move files from it and the computer.
But on my linux computer, I can not see it the reader on the left column.

There is no way to do this.

as Frustated said ADE is not supported on Linux. One of the typical prblems with WINE is that USB connectivty doesn't work
